Cylinder head stud kit
You should consider the strength and reliability of all the critical fasteners
used on your engine. Increased reliability can be obtained for mild states of
tune by replacing the head studs and nuts with uprated versions. The greater
strength of these studs will restrict stretching under pressure and therefore
keep the head and gasket securely in place.

EN24 nickel chrome moly steel studs, competition head stud kit (11 studs,
nuts & washers). This special kit was developed to replace the increasingly
inconsistent standard items. The studs are manufactured in selected hi-grade
steel and produced to exacting specifications. These studs do not stretch, so
they pull the head down, not the thread up, this vastly increases head gasket
life, even on high compression engines. Special thick washers, countersunk on
one side, help clamping capability and reduce thread bottoming of the nuts.
The 12 point skirted nuts help to increase torque accuracy through better
engagement. Note that even replacing the head bolt with a stud, only torque
that stud to the factory recommended spec (25ft/lbs), the other studs can be
torqued to 65ft/lbs with oil, 55ft/lbs with ARP lube.

Solid rocker spacer set
The spacer replaces the springs reducing side loading on the rocker arms
cutting resistance and creating less drag.

Uprated rocker assemblies

Roller rockers are stronger than the standard set up and are designed to
operate the valves with less resistance, these kits also give higher lift than
standard at a ratio of 1.5:1 instead of 1.3:1. Always use with uprated valve
springs and check carefully for clearance.

followers as they mate with the lobe that they run on and should never be
used on another lobe.
Kent performance camshafts
All the Kent camshaft applications/part numbers below with
the suffix ‘P’ are for the original pin drive oil pump/camshaft.
If you have changed your camshaft and oil pump to either ‘Star’ drive or
‘Metro Slot’, use the suffix ‘S’ or ‘M’ on the part number.
To assist in selecting a suitable camshaft we have prepared a table showing
their various characteristics, these will change from engine to engine and
with other modifications such as carburettor or valve size. A scatter profile is
where the cam timing on No. 2 and 3 engine cylinders has been altered
slightly to combat the poor scavenging of the siamese port design. This will
benefit both the tickover and high end performance. The effect of a larger
engine is to lower the camshaft’s power range slightly.
Care must be taken to ensure that installation is carried out correctly and
that components all work together or you will not get the expected power
Lightened and Tuftrided followers wear more slowly and put less load on
high lift cam lobes, they are also manufactured with a drainage hole.
Another essential is the special lubricant that must be used with all new
cams, it provides vital lubrication during initial starting and protects your
cam from extreme wear in its first minute of use.
Camshaft accessories
Don’t forget the camshaft assembly lubricant or the cam timing degree disc,
you will need this to set your cam timing.
